Title: Sharp Cam gears, how bad?
Post by: fiftytakedowns on August 06, 2009, 01:44:06 PM: When relpacing my valve cover gasket I noticed my cam gear (chain gears) teeth were sharp, I know this is quite bad, but wondered How bad, and what I should do to fix it

Is it alright to replace the cam sprokets (sp?), and the timing chain tensioner, and not the chain?

Thanks,

fitty ts

The teeth were sharp but not horrid,
would doing an m44 timing chain tensioner be a smart move for now.....

No, don't install the M44 tensioner. It'll just accelerate the wear at this point. Start looking for a swap.

My understand of the M42 timing gear is that the teeth get sharp because of a stretched chain. There is no permanent solution other than replacing the chain, gears and rails and tensioner all together. Replacing just the tensioner now can push a weak chain over the edge.
good luck

Title: Sprockets & chain
Post by: P. Kennedy on October 10, 2009, 11:43:28 AM: I have virtually new cam sprockets and chain for sale if that would help you out. Though, it's a fairly time consuming task.

Post by: P. Kennedy on October 10, 2009, 09:57:24 PM: Barely. Couple hundred miles is my guess. Nice and square at the top of the teeth. I can send photos if you want.

Post by: fiftytakedowns on October 11, 2009, 04:42:12 AM: how much for chain? I already have the sprockets, do you have any other of the parts?
Title: Timing chain
Post by: P. Kennedy on October 11, 2009, 07:32:44 PM: Well, Pelican Parts want $59 + shipping for it; the st(dealer) wants $135!

How about $40 shipped?

I don't have any other parts to spare.

Post by: fiftytakedowns on October 12, 2009, 08:40:44 PM: Im thinkin about it,
it is used, and usually you want to break in the chain to the rest of the system: and if Im down there I should probably use new parts anyway.
